You will have to monitor BOTH high and low charge while system is running.
If you have 100 low static pressure the low pressure switch should be activated. Use an ohmmeter across the switch to confirm. If it is made and the compressor is still not on, measure voltage at switch. If there is none, go back to the CCU and check for power to it.

But at the moment, I can't get the system running to verify the pressures. Right now, the blower motor won't even turn on, so I'm just wondering where to check (fuses, short in wire, etc) to get the blower motor running again before I tackle the ac problem?
